Product Description:

4-Iodobiphenyl is an organic compound consisting of a biphenyl core substituted with an iodine atom at the para position. It is a white to off-white crystalline solid with a molecular formula of C12H9I. This compound is a versatile building block in organic synthesis, particularly valued for its halogenated aromatic structure. Its primary and most significant application is in the field of materials science, specifically as a key precursor for the synthesis of organic light-emitting diodes (OLEDs) and other organic electronic materials. The iodine atom serves as an excellent handle for cross-coupling reactions, such as Suzuki, Heck, or Ullmann couplings, enabling the efficient construction of extended π-conjugated systems, which are fundamental to charge transport and light emission in OLED devices. It is used to synthesize various hole-transporting materials (HTMs), host materials, and emissive layer components. Beyond its role in advanced materials, 4-iodobiphenyl is also a common and useful reagent in general organic chemistry for constructing biaryl systems. It requires careful handling due to its potential toxicity and should be stored away from light.
